【Java】已解决：org.springframework.beans.BeanInstantiationException

一、分析问题背景 org.springframework.beans.BeanInstantiationException 是在Spring框架中使用依赖注入时常见的异常。...二、可能出错的原因导致org.springframework.beans.BeanInstantiationException报错的原因有很多，以下是常见的几种：构造函数参数不匹配：Spring在实例化...三、错误代码示例以下是一个可能导致BeanInstantiationException的错误代码示例，并解释其错误之处： @Component public class MyService {...} 错误分析：构造函数参数不匹配：在AppConfig类中，myService方法尝试创建MyService实例时，没有传递MyRepository参数，导致Spring无法找到匹配的构造函数，抛出BeanInstantiationException...通过遵循以上步骤和注意事项，可以有效解决org.springframework.beans.BeanInstantiationException报错问题，确保Spring应用程序的正常运行。

版本兼容导致的java.lang.NoClassDefFoundError: orgspringframeworkdataspelExpressionDependencies

在使用spring-data-cassandra时，因为springboot版本与spring-data-cassandra版本不兼容导致启动时报了下面的异常信息 java.lang.NoClassDefFoundError...: org/springframework/data/spel/ExpressionDependencies 笔者使用的springboot版本为2.3.7.RELEASE，最初使用的spring-data-cassandra...版本为3.1.2，在spring-data-cassandra 3.1.2版本我们可以看到下面一段文字： 6.2....但是springboot 2.3.7版本依赖的spring Framework版本为5.2.12版本，所以解决这个版本冲突问题有两种方式： 1、升级springboot版本 2、降级spring-data-cassandra...版本为3.0.6版本 3、使用spring-boot-starter-data-cassandra代替spring-data-cassandra，因为已经使用springboot，最好的方式还是使用springboot

spring-data-cassandra 实体类中字段不与数据库表映射

在使用spring-data-cassandra实体模型时有时为了减少一些类同时又可以传递一些非数据库字段的信息，这时我们可以使用@Transient注解来实现，但需要注意的使用的@Transient注解并不是...Transient注解，而是org.springframework.data.annotation包下的@Transient注解，该注解是spring-data-commons下的注解，使用transient关键字在spring-data-cassandra
